To all whom it may concern.'

Ee it known that we, Geenen S. Sevierville and CHARLne E. Mvnns, both citizens ot the United States, and residents of the city of St. Louis and State ot Missouri, have invented a certain new-and useful Improvement in Thread-Treating Devices for Sewing-Machines, et which the following is a specitication.

The subject matter ofthe present invention is divided out of an application tor Letters Pat-ent for an improvement in sewing machines, Serial No. 501,462, filed by ns on June 11, 1969. s

The present invention relates to thread treating devices for sewing machines.

lt has for its principal objects to avoid the disadvantages incident to a waxed or treated thread hardening before reaching the stitch .torniing mechanism; `to obviate the necessity or passing the waxed or treated thread through the tension, take up and \-4,-- N s a several guiding devices; and to attain certain advantages hereinafter more fully appeering.

The invention consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

ln the accompanying drawings which term part or this specilication, and wherein like symbols refer to like parts wherever they occur, Figure 1 is a view, partly in side elevation and partly in vertical section,l of a portion of a sewing machine which is provided with a thread treating device embodying our invention; Fig.- 2 is a View, partly in front elevation and partly in vertical section, showing the thread treating device in full lines and the other parts ofthe machine in dotted lines; Fig. 3 is a fragmentary side elevation of the needle threadmember of the treating device; Fig. 4 is a longitudinal section of the parts of the needle thread member det-ached; Fig. 5 is an end View of said member; and Figs. 6, 7 and 8 are diagrammatic views showing the dill'erent positions of the controlling valve for the treating device.

For the purposes of illustration the thread waxing or treat-ing device is shown in the accompanying drawings as applied to the lockloop stitch sewing machine set forth in our application for Letters Patent, Serial No. 501,462, hereinbefore referred to. nly the parts of the machine which are directly'v associated with the be herein set forth.

As shown iinthe accompanying drawing", the machine comprises a base 1 having a standard 2 thereon. 0n this standard is a circular housing 3 having flat-tened side walls. Extending transversely through the center of the housing is a shaft- 4. A segment gear 5 having two oppositely disposed present invention will segmental extensions 6, 7, is xedly mounted on the base 1. The block is provided with a laterally projecting stud or roller`15 which is adapted to coperatie with a cam groove in a rotary disk (not shown) whereby a reciprocatory motion is imparted to the block when the disk is rotated.

Pivotally mounted on the segmental extension 6.0i the segment gear 5 is a curved awl 1G. The awl is arranged lto cooperate with certain devices within the housing so that it is oscillated laterally at the same time it is reciprocated by the oscillation of the segment gear 5 upon which it is mounted. By this means, the work is intermittently fed forward each time the awl pierces it so as to bring the puncture in t-he path of lthe needle. The needle 17 is fixedly mounted on the segmental extension 7 of the segment gear 5; and both the needle and the awl are curved on the same radius from the axis of the shaft 4.

The upper front portion of the housing 3 is cut away to provide space for a work table orsupport which preferably comprises a horizontal plate 18. This plate is firmly secured to the housing and it is provided with a slot through which the awl and needle work. A carrier 19 for the locking-loop patented ll-leb. 6, 191% I stitch,

thread is slidably mounted in a horizontal guldeway in or under the table 18 and it is intermittently actuated. It has a hoolr por tion which is reciprocated across the slot in the table so as to lay a loop ofv the lookin O thread through a loop ofthe needle thread which is carried through the work by the needle. The stitch is set or completed by pulling the needle thread so as to interlock the two loops ot thread and draw the same into the puncture in the work. rllhis is ac` complished by a take-up device comprising an oscillatory arm 20 which is fixedly mounted on the end portion of the rock shaft 4 out* side .ot-the housing 3. 0n this oscillatory arm 1s arranged a suitable thread guide with which a pivoted cam. or other suitable gripping member cooperates. The take-up is arranged so that the thread is free to pass therethrough except durin the time it is actuated to pull the threa in setting the The thread treating or waxing material is used in a fluid state, preferably an ethereal solution or" a viscid substance or a cement which becomes hardened when exposed to the atmosphere. This material is lled into the lower. portion ot' a reservoir which is mounted on some convenient part of the machine. .The reservoir 21 is preferably mounted on a bracket which is secured to the underside of the base 1. The supply spools A and B for the needle thread A and the locking loop thread B, respectively, are also preferably mounted on the bracket .which supports the reservoir. rlhe reservoir is provided with a, suitable lilling nipple 22 which 1s closed by a removable lscrew plug 23. Leading from the bottom portion of the reservoir is a pipe 24 having a suitable cut-oit or valve 25. A valved nipple or tube 26 is provided at the top of the reservoirthrough which air may be forced into the reservoir and compressed above the liquid material therein so that when the valve 25 in the pipe 24 is opened, the liquid in the reservolr willbe forced out through said pipe. The pipe 24 is extended upward and connected by a suitable'coupling 27 to a depending pipe extension V28 of an elongated tubular valve-casing 29 which is located near the top side of the base 1. In this tubular valve-casing is rotatably fitted a tubular valve 30 which is closed by a plug 31 at its inner'end, as shown in Fig. 1. The plug is tightly fitted into the end of the tubular valve and it is provided with an annular shoulder or collar 32 which bears against the end of the valve-casing and serves to recasing to a thread-guide and waxingv or treating device. 37. The openings in the valve 30 and pipes 28, 36 are arranged so that in one position of the valve, c immuni-QI cation is established between the reservoir 21' and the device 37 through the pipe 24,

pipe 28, valve 30 and pipe36.

The waxing ortreating device comprises an elongated, downwardly and outwardly The bottom of this groove is preferably inclined toward the lower end of the member which isset at an angle so that the bottom of the groove is on a line substantially tangential to the outer side ofthe curved needle 17. The intermediate portion of the bottom of the groove is krecessed or channeled slightly, as at 40; and ,into this channel portion the pipe 36 communicates through an opening 41 in the upper portion of the member 38. Slidably fitted on the member 38 is a sleeve 42 having a tapered longitudinal rib 43 which is adapted to it in the Agroove 39 in said member 38. The inclination of the edge of the tapered rib corresponds to the inclination of the bottom of' the groove so that the two surfaces are in parallel relation. By moving the sleeve 42 longitudinally of the member 38 the distance between the bottom of the groove and the edge of the rib may be widened and lessened when desirable or necessary. A rib or other suit-V on' the outer side of the sleeve 42 for conveniently manipulating the device.

In practice, it is preferable to pass the needle thread A thraugh the waxing or treating device at all times whether the thread is to be treated or not. Provision has, therefore, been made to shut oft the supply of waxing or treating material at the will of the operator, as hereinafter described. In the operation of the device, the sleeve 42 is removed from the member 38 and the end portion of the needle thread A is laid in the groove 39 'in said member 38.

lThe sleeve 42 is then slipped onto the member 38 until the thread is slightly compressed between the bottom of the end portions of the groove 39 and the edge of the rib 43 which is fitted in said groove. The pressure on the thread is suflicientto produce a slight resistance when said thread is pulled through the device. The end/of the needle thread A is, of course, passed-through theeye of'the needle 17 and the stitches are made in the manner hereinbefore set forth. If it is desired to wax or' treat the thread that4 goes into the work, the valve 30v is turned open communication betweentthe reservoir 21 and the device 37, whereupon the, liquid lmaterial will be forced from uthe reservoir Leieeei 53 by the eir pressure behind it. As the thread o lied through the device 37, it becomes rated or coated depending upon the netui'e end consistency of the materiel which 'tloivs into the channel portion or the groove vin member 3? under pressure. The lower cooperating portions et the rib e3 und the member 3S serve es' e, stripper to remove surplus materiel from the 'thread as it leaves the device, and also prevents the materiel from or oozing out. when the device is properly adjusted or t glitened on thread. When it is desired to use :i dry or untreated t? Toad, itis only necessary to turn the valve 5o 'to shut oirn the supply of liquid materiel from the reservoir.

The Waxing or treating device tor the locking-loop thread B comprises e recepte- .receptacle lil/fixen it' v 'untreated thread,

1 h fw fm'e ti' cie oi c amber lo. lois iecep `ziele is preiei ably mounted on the valve casing 29 and 'communicates with the interior thereof,

through in opening' e6 which is arranged to ieglstei"ivith ein opening 4:7 in the tubular valve 30. `When it is desired to supply Wen ing or treating nidterial to the receptacle, 'the valve 30' is turned to open communicw tion through its'opening 4.7 end opening 46 into the receptacle 45, and also between t`-e opening and pipe 28. fllhe" liquid materiel from the reservoir Will then be forced up into the receptacle and when the necessary ernennt shell have l een supplied 'thereto, the telve isv turned to close communica- ""on between the receptacle 'sind the reser cover i8 of the recepteeie i5 is roede couille and may be secured in any desire manner. Slidebly mounted in e vertical opening in the cover L18 is fi thread holder Y, guide comprising :i rod i9 having uy cent or laterally -turned end portion 'enrich is looped or provided with an eye 5l "'irougii Awhich locking-loop thread B is passed. Gn the outer end of the rod i9 is e knob 52 rv'hciel j,"the Sonie can easily be inanipuleted. in order to hold the in lor,Tu ered or iinA `iersed position, hooked lateral extension 53 is provided on the outer end portion thereof so es to engage in o loop or retaining device 5e secured to the top of the receptacle. The thread B is teken up through on opening in the bese l, from the suppl;v spool B., thence inwardly throuoh o curved tube 55 in the top of the receptacle 45, thence through the loop 5l on the lower end of the ,rod 4:9, thence outwardly tl'irough straight tube 5- 6 in the top receptie cle, endl 'thence to the' locking-loop lcerriin hooi; i9. lWhen it is desired to wei: or treat the thread B the rod 49 is lowered immerse its loop or its eye 5'?. io the liquid material in the receptacle. The thread thereby passed through the material in the is desired to use e dry the'rod t9 is raised to bring the bent end close to the top of the r cepte'cle end above the level of' the liquid therein.

rEhe openings in the vel v'e 30 are so errenged their when communication is estab lished between the reservoir 2l end the Waxing device ,communication is cut oil between the reservoir end the receptacle 45, and vice verso; und that the vulve may be turnedto out ofi communication between the `reservoir end both the 'Waxing device 37 and the receptacle l5 et the seme time. To indicete the proper positions of the valve 'the handle portion 57 thereof is provided with e pointer orindicator 58 which is adapted to cooperate with e dial "it on the outer end of the valve casing.
